Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds for container manufacturing, and in particular to a mold structure for cigarette box manufacturing. Background Technology
[0002] A cigarette case is a box for holding cigarettes. For ease of carrying, cigarette cases are generally available in packs of 5, 7, 10, 14, or 20 cigarettes. They are made of materials such as paper, aluminum, and tinplate.
[0003] Starting in 2005, tobacco companies turned their attention to tinplate cigarette boxes due to their novel designs, exquisite printing, durability, and ease of transport, making them popular with consumers. Currently, the main structure of tinplate cigarette boxes includes a bottom and a lid. The bottom requires processes such as flashing, pre-bending, winding, flattening, and hinge during stamping, while the lid requires similar processes. Each of these processes uses a separate set of molds. Therefore, cigarette box production requires a large number of molds and stamping presses, resulting in high equipment costs and numerous material transfers, leading to poor production continuity and low efficiency. Therefore, it is necessary to research a solution to these problems. Utility Model Content

[0051] The working principle of this embodiment is described in detail below:
[0052] When manufacturing the box bottom 31, the first metal sheet for manufacturing the box bottom 31 is sequentially placed onto the bottom flash lower module 112, the bottom pre-bending lower module 113, the bottom coiling lower module 114, the bottom flattening lower module 115, and the bottom hinge lower module 116. Each opening and closing of the first upper die 12 and the first lower die 11 completes the stamping of one box bottom 31. Specifically, the closing of the bottom flash upper module 122 and the bottom flash lower module 112 completes the flashing of the first metal sheet. The bottom pre-bending upper module 123 and bottom pre-bending lower module 113 are molded together to pre-bend the first metal sheet. The bottom coiling upper module 124 and bottom coiling lower module 114 are coiled to form the first metal sheet. The bottom flat upper module 125 and bottom flat lower module 115 are flattened to form the first metal sheet. The bottom hinge upper module 126 and bottom hinge lower module 116 are hinged to form the first metal sheet, thus forming a hinged structure.
[0053] When manufacturing the lid 32, the second metal sheet material for the lid base 32 is sequentially placed onto the lid flash lower module 212, lid corner cutting lower module 213, lid pre-bending lower module 214, lid coiling lower module 215, lid flattening lower module 216, and lid pressing lower module 217. Each opening and closing of the second upper mold 22 and the second lower mold 21 completes the stamping of one lid 32. Specifically, the lid flash upper module 222 and the lid flash lower module 212 close to form the flash of the second metal sheet material, and the lid corner cutting upper module 223 and the lid cutting lower module 217... The corner lower module 213 completes the corner cutting and forming of the second metal sheet by closing the mold. The cover pre-bending upper module 224 and the cover pre-bending lower module 214 complete the pre-bending and forming of the second metal sheet by closing the mold. The cover coiling upper module 225 and the cover coiling lower module 215 complete the coiling and forming of the second metal sheet by closing the mold. The cover flat upper module 226 and the cover coiling lower module 215 complete the flattening and forming of the second metal sheet by closing the mold. The cover rice-making upper module 227 and the cover rice-making lower module 217 complete the rice-making and forming of the second metal sheet by closing the mold, so as to form a convex structure.
[0054] Finally, by hingedly connecting the lid 32 and the bottom 31 together, the cigarette box 30 can be obtained.
[0055] The key design feature of this invention is that by setting various modules on the lower mold base and the upper mold base, the first mold assembly can complete all the manufacturing processes of the bottom of the cigarette box. In conjunction with setting various modules on the lower mold base and the upper mold base, the second mold assembly can complete all the manufacturing processes of the lid of the cigarette box. This greatly reduces the number of molds and punches, thereby reducing equipment costs. At the same time, materials do not need to be transferred multiple times, resulting in excellent production continuity and greatly improved production efficiency.
